In at least one implementation, an application that generates a web service request is executed on a wireless communication device. The wireless communication device executes a client security component of the application to collect security information and include the security information in the web service request, and utilizes a mobile application programming interface to transfer the web service request including the security information for delivery to a web server. The web server executes a server security component of a web service to extract the security information from the web service request, validate the web service request based on the security information, and provide the web service request to the web service upon successful validation.

RELATED APPLICATIONS

This application claims the benefit of, and priority to, U.S. Provisional Patent Application No. 62/108,117, entitled “NETWORK ATTACK DETECTION ON A MOBILE API OF A WEB SERVICE”, filed Jan. 27, 2015, which is hereby incorporated by reference in its entirety for all purposes.

TECHNICAL BACKGROUND

Traditional web services that are accessed by a web browser typically utilize hypertext markup language (HTML) and Javascript, which provide the capability to determine legitimate use of the web service, such as presenting Completely Automated Public Turing tests to tell Computers and Humans Apart (CAPTCHAs) and other challenge questions to the user. However, unlike traditional web services, wireless communication devices often employ mobile applications to communicate with web servers. For example, typical mobile applications pull data down from web servers for display to the user, and also allow the user to modify the data and submit it back to the server.

Mobile applications commonly utilize mobile application programming interfaces (APIs) to communicate with external web services and provide their functionality to the user. The communication between native mobile applications and mobile APIs on the web servers is typically done using JavaScript Object Notation (JSON), Extensible Markup Language (XML), and other protocols that do not employ security techniques but are simply used to provide an exchange of data between the client and server. Thus, the core application communication between the mobile application and the web service utilizes a mobile API with no security in place to validate the legitimacy of the request. Unfortunately, these weaknesses are easily exploited to bypass the security solutions used on traditional web services and allow unauthorized communication with web servers using the mobile API, subjecting the web service to possible malicious use.

Mobile applications are software programs that are designed to be executed on mobile computing systems, such as smartphones, tablets, and other wireless communication devices. A mobile application typically communicates with a web server using a mobile application programming interface (API) to exchange data between the client and the server. However, these data exchanges are typically unsecured, and cannot utilize the security techniques employed by traditional web browsers that use HTML and Javascript. As a result, mobile application data exchanges are more vulnerable to unauthorized use and attacks by malicious actors.

Implementations are disclosed herein to validate web service requests from mobile applications executing on wireless communication devices. In at least one implementation, security information about a device executing a mobile application and its operating environment are collected from within the mobile application. The mobile application can then send the security information to a server for processing and validation of a web service request.

FIG. 1 is a block diagram that illustrates communication system 100. Communication system 100 includes wireless communication device 101, communication network 120, and web server 130. Wireless communication device 101 and communication network 120 communicate over communication link 121. Communication network 120 and web server 130 are in communication over communication link 131.

In operation, wireless communication device 101 executes an application that collects security information at runtime from wireless communication device 101 and its operating environment. In some implementations, the security information collection process may be performed by a client security component embedded into the application. The security information collected by the application may relate to device attributes such as hardware components that are present or absent in wireless communication device 101 and the operating environment in which the application is running, user behavior attributes indicative of how a user is operating wireless communication device 101, unique transaction identifiers, and other security information. Presence or absence of a combination of these attributes can be used to validate a web service request submitted by the application executing on wireless communication device 101. An exemplary implementation for validating a web service request from an application executing on wireless communication device 101 will now be discussed with respect to FIG. 2.

FIG. 2 is a flow diagram that illustrates an operation 200 of communication system 100. The operation 200 shown in FIG. 2 may also be referred to as validation process 200 herein. The steps of the operation are indicated below parenthetically. The following discussion of operation 200 will proceed with reference to wireless communication device 101 and web server 130 of FIG. 1 in order to illustrate its operations, but not that the details provided in FIG. 1 are merely exemplary and not intended to limit the scope of process 200 to the specific implementation shown in FIG. 1.

Operation 200 may be employed by wireless communication device 101 and web server 130 to facilitate validation of web service requests from applications executing on wireless communication device 101. As shown in the operational flow of process 200, wireless communication device 101 executes an application that generates a web service request (201). The application could comprise any software application that may be executed on wireless communication device 101. For example, the application could comprise a streaming media application, video application, audio application, news client, gaming application, sports application, social media application, web browser, messaging application, or any other software application—including combinations thereof. The web service request is typically generated by the application in response to some user input, such as a user launching the application, clicking a link presented by the application, entering data into a form field on the application for submission to web serve 130, or responsive to any other user action. However, in some examples, the web service request could be automatically generated by the application, including in response to a request from another application. Typically, the web service request comprises instructions to direct a web service to either retrieve data from web server 130 and/or instructions to store data transferred by wireless communication device 101 in web server 130. For example, the web service request could comprise a query, message, notification, command, request, instruction, or any other communications between wireless communication device 101 and web server 130, including combinations thereof.

Wireless communication device 101 executes a client security component of the application to collect security information and include the security information in the web service request (202). The client security component of the application typically collects the security information from wireless communication device 101 for inclusion in the web service request. For example, the client security component may determine device attributes of wireless communication device 101, observe user interactions with the application, monitor network access requests and data traffic, and determine historically run and currently running applications and other usage of wireless communication device 101, among other techniques of determining the security information. In some examples, the security information could comprise device attributes, such as a user identifier, device identifier, telephone number, Media Access Control (MAC) address, Electronic Serial Number (ESN), Mobile Station Identifier (MSID), Mobile Equipment Identifier (MEID), Mobile Station International Subscriber Directory Number (MSISDN), International Mobile Equipment Identity (IMEI), International Mobile Subscriber Identity (IMSI), or any other device information —including combinations thereof.

The security information could also include user behavior attributes gleaned from the manner in which wireless communication device 101 is utilized. For example, the user behavior attributes could include the type and number of applications that have historically run and are currently running on device 101, operating system and device management functions, and behavior that indicates usage of wireless communication device 101 by a human operator, such as the velocity and sequence of navigation between various views, displays, pages, or other content of an application or applications, the speed of user input, such as the time between keystrokes or other user commands, and any other information indicative of device usage. The security information could also include unique transaction identifiers and factors indicative of wireless communication device 101 having physical hardware, which may be determined by detecting hardware components present in the wireless communication device. Some examples of factors that may be indicative of wireless communication device 101 having physical hardware could include device activation and boot time, date and time when the application was installed, list of all applications installed on device 101, list of running applications, presence of a camera, presence of wireless radio signals such as Bluetooth, Wi-Fi, and others, and the presence of multiple entries in a contact list, photo album, messaging application, email inbox, or other applications. The security information could further include device power status, remaining battery power, network status, presence of application stores installed on device 101 that may be used to download new or updated applications, and any other information that may be used to determine the physical nature of wireless communication device 101, including combinations thereof. Note that the factors listed above are merely exemplary, and additional attributes that may be used to determine the legitimacy of the request could be included in the security information and are within the scope of this disclosure.

The application executing on wireless communication device 101 then utilizes a mobile application programming interface (API) to transfer the web service request including the security information for delivery to web server 130 (203). Typically, the mobile API is used as an interface to exchange data between an application executing on device 101 and a web service provided by web server 130. However, since the mobile API typically allows this data exchange to occur without regard to security, web server 130 may utilize the security information included in the web service request to verify and validate the request. In at least one implementation, the client security component of the application embeds the security attributes into the web service request before the request is transferred to web server 130. The security information may be transparent to the application, the mobile API, and the web service in some examples.

Web server 130 executes a server security component of a web service to extract the security information from the web service request, validate the web service request based on the security information, and provide the web service request to the web service upon successful validation (204). The server security component of the web service verifies and processes the security information to determine a legitimate or malicious request. Typically, the server security component analyzes all of the attributes in the security information to validate the web service request. For example, the presence of multiple factors could indicate whether the request appears legitimate or malicious. All of the attributes listed above do not need to be present in the security information for the security component of the web service to determine if the web service request is legitimate, but each factor strengthens the determination. In some implementations, a threshold number of attributes could be used to determine when enough of the attributes exist to determine the legitimacy of the request. For example, the server security component could compare a total number of the attributes received in the security information to a threshold number of attributes to determine the legitimacy of the web service request submitted by wireless communication device 101 when the total number of the attributes exceeds the threshold number. The greater the number of attributes present in the security information of web service request, the higher the likelihood that the application and its request are legitimate, so the threshold number of attributes could be increased to provide greater security protection for the web service. Once the request is validated, the server security component of the web service removes the security information from the web service request and provides the request to the web service. In this manner, the security information and request validation remain transparent to the web service, thereby not requiring any modifications to the communication protocol and mobile API used between the application and the web service.

Advantageously, the client security component of the application transparently adds security information to web service requests when the application communicates with a web service using a mobile API. The security information included in the web service request allows the server security component of the web service to ensure that only genuine native applications with legitimate user behavior are allowed to use the web service, and any possible exploitation of the mobile API to perform malicious actions can be blocked. By securing the web service from malicious use, the techniques described herein provide the technical advantage of reducing the load on the processor, network components, and other elements of web server 130 by eliminating illegitimate requests, while also safeguarding the information of users of the web service. Further, because the security information collection, exchange, and processing is handled transparently by the security components of the application and the web service, these two endpoints are unaware of the additional security information and validation that occurs to safeguard the information exchange. In this manner, the web service has a higher degree of confidence in the legitimacy of the web service request, and possible exploitation of the mobile API to perform malicious actions can be blocked in the alternative.

Referring back to FIG. 1, wireless communication device 101 may comprise any device having wireless communication connectivity with hardware and circuitry programmed to function as a telecommunications device, such as Radio Frequency (RF) communication circuitry and an antenna. The RF communication circuitry typically includes an amplifier, filter, modulator, and signal processing circuitry. Wireless communication device 101 may also include a user interface, memory system, software, processing circuitry, or some other communication components. For example, wireless communication device 101 could comprise a telephone, transceiver, mobile phone, cellular phone, smartphone, computer, personal digital assistant (PDA), e-book, game console, mobile Internet device, wireless network interface card, media player, or some other wireless communication apparatus—including combinations thereof. Wireless network protocols that may be utilized by wireless communication device 101 include Code Division Multiple Access (CDMA) 1xRTT, Global System for Mobile communications (GSM), Universal Mobile Telecommunications System (UMTS), High-Speed Packet Access (HSPA), Evolution-Data Optimized (EV-DO), EV-DO rev. A, B, and C, Third Generation Partnership Project Long Term Evolution (3GPP LTE), LTE Advanced, Worldwide Interoperability for Microwave Access (WiMAX), IEEE 802.11 protocols (Wi-Fi), Bluetooth, Internet, telephony, or any other wireless network protocol that facilitates communication between wireless communication device 101 and a communication network.

Communication network 120 could comprise multiple network elements such as routers, gateways, telecommunication switches, servers, processing systems, or other communication equipment and systems for providing communication and data services. In some examples, communication network 120 could comprise wireless communication nodes, telephony switches, Internet routers, network gateways, computer systems, communication links, or some other type of communication equipment—including combinations thereof. Communication network 120 may also comprise optical networks, asynchronous transfer mode (ATM) networks, packet networks, local area networks (LAN), metropolitan area networks (MAN), wide area networks (WAN), or other network topologies, equipment, or systems—including combinations thereof. Communication network 120 may be configured to communicate over metallic, wireless, or optical links. Communication network 120 may be configured to use time-division multiplexing (TDM), Internet Protocol (IP), Ethernet, optical networking, wireless protocols, communication signaling, or some other communication format—including combinations thereof. In some examples, communication network 120 includes further access nodes and associated equipment for providing communication services to several computer systems across a large geographic region.

Web server 130 comprises a processing system and communication transceiver. Web server 130 may also include other components such as a router, server, data storage system, and power supply. Web server 130 may reside in a single device or may be distributed across multiple devices. Web server 130 may be a discrete system or may be integrated within other systems—including other systems within communication system 100. In some examples, web server 130 could comprise a network switch, router, switching system, packet gateway, network gateway system, Internet access node, application server, database system, service node, firewall, or some other communication system—including combinations thereof.

Communication links 121 and 131 use metal, air, space, optical fiber such as glass or plastic, or some other material as the transport medium—including combinations thereof. Communication links 121 and 131 could use various communication protocols, such as TDM, IP, Ethernet, telephony, optical networking, hybrid fiber coax (HFC), communication signaling, wireless protocols, or some other communication format—including combinations thereof. Communication links 121 and 131 could be direct links or may include intermediate netwocks, systems, or devices.

FIG. 3 is a flow diagram that illustrates an operation of communication system 100 in an exemplary embodiment. The techniques described in FIG. 3 could be executed by the elements of communication system 100 and could be combined with operation 200 of FIG. 2 in some implementations. FIG. 3 is divided into two sections, separated by a dotted line. The top half of FIG. 3, labeled “Traditional Unsecure Mobile-To-Web Service Communication”, illustrates a typical, unsecure data exchange between a native mobile application executing on wireless communication device 101 and a web service provided by web server 130. Traditional web services that are accessed by a web browser typically utilize hypertext markup language (HTML) and Javascript, which provide the capability to bundle code along with the data that may be used to determine legitimate use of the web service, such as presenting Completely Automated Public Turing tests to tell Computers and Humans Apart (CAPTCHAs) and other challenge questions to the user.

However, native mobile applications utilize mobile APIs to communicate with external web services and provide their functionality to users. Typically, most of the data utilized by a mobile application resides on the server, and the server also commonly performs operations on the data such as addition, deletion, and modification, often in response to a user request made to the application. The communication between native mobile applications and mobile APIs on the web servers is typically done using JavaScript Object Notation (JSON), Extensible Markup Language (XML), and other protocols that do not employ security techniques but are simply used to provide an exchange of data between the client and server. Thus, the core application communication between the mobile application and the web service utilizes a mobile API with no security in place to validate the legitimacy of the request. Unfortunately, these weaknesses are easily exploited to bypass the security solutions used on traditional web services and allow unauthorized communication with web servers using the mobile API, subjecting the web service to possible malicious use. For example, a malicious user could attempt unauthorized user login, fake account creation, fraudulent data submission to the server, data theft from the server by impersonating a user/device, and others.

Turning now to the lower portion of FIG. 3, labeled “Secure Mobile-To-Web Service Communication”, security components are added to the native client application as well as the web service. In FIG. 3, the security component added to the mobile application is designated as client side (CS), and the security layer added to the web service is designated as server side (SS). When a legitimate native mobile application communicates with the web service, the CS security layer transparently injects additional security information to the communication, including device attributes, user behavior attributes, unique transaction identifiers, and others. This security information is then verified by the SS security layer and used to determine legitimate or malicious intent. Upon determining legitimate intent, the SS security layer then strips off the security information from the web request before the request is provided to the actual web service. In this manner, the security information and validation determination remain transparent to the mobile application and the web service, allowing them to utilize the original communication protocol used to exchange data between the mobile application and the web service without modification. As such, the two endpoints are unaware that the injection and filtering of additional security information has occurred. The CS and SS security layers work to ensure that only legitimate native mobile applications with clean user behavior are allowed to use the web service, and any possible exploitation of mobile APIs is blocked.

Beneficially, the CS security component transparently adds additional security information to a web request when a native mobile application communicates with web services using mobile APIs. The security information is then inspected, validated, and filtered by the SS security component at the web server as described above, thereby securing the mobile APIs used by the mobile application.

FIG. 4 is a block diagram that illustrates wireless communication device 400. Wireless communication device 400 provides an example of wireless communication device 101, although device 101 could use alternative configurations. Wireless communication device 400 comprises wireless communication transceiver 401, processing system 402, and user interface 403.

Wireless communication transceiver 401 may use various protocols, such as CDMA, GSM, UMTS, EV-DO, EV-DO rev. A, 3GPP LTE, LTE Advanced, WiMAX, Bluetooth, Internet, telephony, or some other wireless communication format.

Processing circuitry 404 may be embedded in various types of equipment. Processing circuit 404 is typically mounted on a circuit board that may also hold memory system 405 and portions of wireless communication transceiver 401 and user interface 403. Memory system 405 comprises a non-transitory computer readable storage medium, such as a disk drive, flash drive, data storage circuitry, or some other hardware memory apparatus. Memory system 405 may comprise a single device or could be distributed across multiple devices—including devices in different geographic areas. Memory system 405 may be embedded in various types of equipment. In some examples, a computer apparatus could comprise memory system 405 and operating software 406. Operating software 406 comprises computer programs, firmware, or some other form of machine-readable processing instructions. Operating software 406 may include an operating system, utilities, drivers, network interfaces, applications, or some other type of software. In this example, operating software 406 comprises application 407, although software 406 could have alternative configurations in other examples.

When executed by processing circuitry 404, operating software 406 directs processing system 402 to operate wireless communication device 400 as described herein for wireless communication device 101 when executing validation process 200 or variations thereof. In particular, operating software 406 may direct processing system 402 to execute application 407 that generates a web service request. Further, operating software 406 may direct processing system 402 to execute a client security component of application 407 to include security information in the web service request. In addition, operating software 406 may direct processing system 402 to utilize a mobile application programming interface to transfer the web service request including the security information for delivery to a web server.

Referring now to FIG. 5, a block diagram that illustrates computing system 500 in an exemplary implementation is shown. Computing system 500 provides an example of web server 130, although server 130 could use alternative configurations. Computing system 500 could also provide an example of wireless communication device 101, although device 101 could use alternative configurations. Computing system 500 includes processing system 501, storage system 503, software 505, communication interface 507, and user interface 509. Software 505 includes application 506 which itself includes validation process 200. Validation process 200 may optionally be implemented separately from application 506.

Computing system 500 may be representative of any computing apparatus, system, or systems on which application 506 and validation process 200 or variations thereof may be suitably implemented. Examples of computing system 500 include mobile computing devices, such as cell phones, tablet computers, laptop computers, notebook computers, and gaming devices, as well as any other type of mobile computing devices and any combination or variation thereof. Note that the features and functionality of computing system 500 may apply as well to desktop computers, server computers, and virtual machines, as well as any other type of computing system, variation, or combination thereof.

Computing system 500 includes processing system 501, storage system 503, software 505, communication interface 507, and user interface 509. Processing system 501 is operatively coupled with storage system 503, communication interface 507, and user interface 509. Processing system 501 loads and executes software 505 from storage system 503. When executed by computing system 500 in general, and processing system 501 in particular, software 505 directs computing system 500 to operate as described herein for wireless communication device and/or web server 130 for execution of validation process 200 or variations thereof. Computing system 500 may optionally include additional devices, features, or functionality not discussed herein for purposes of brevity.

Referring still to FIG. 5, processing system 501 may comprise a microprocessor and other circuitry that retrieves and executes software 505 from system 503. Processing system 501 may be implemented within a single processing device but may also be distributed across multiple processing devices or sub-systems that cooperate in executing program instructions. Examples of processing system 501 include general purpose central processing units, application specific processors, and logic devices, as well as any other type of processing device, combinations, or variations thereof.

Storage system 503 may comprise any computer readable media or storage media readable by processing system 501 and capable of storing software 505. Storage system 503 may include volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information, such as computer readable instructions, data structures, program modules, or other data. Storage system 503 may be implemented as a single storage device but may also be implemented across multiple storage devices or sub-systems co-located or distributed relative to each other. Storage system 503 may comprise additional elements, such as a controller, capable of communicating with processing system 501. Examples of storage media include random-access memory, read-only memory, magnetic disks, optical disks, flash memory, virtual memory and non-virtual memory, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and that may be accessed by an instruction execution system, as well as any combination or variation thereof, or any other type of storage media. In no case is the storage media a propagated signal.

In operation, in conjunction with user interface 509, processing system 501 loads and executes portions s of software 505, such as application 506 and/or validation process 200, to validate web service requests from applications executing on wireless communication devices. When representative of web server 130, software 505 may be implemented in program instructions and among other functions may, when executed by computing system 500 in general or processing system 501 in particular, direct computing system 500 or processing system 501 to execute a server security component of a web service to extract security information from a web service request, validate the web service request based on the security information, and provide the web service request to the web service upon successful validation. When representative of wireless communication device 101, software 505 may be implemented in program instructions and among other functions may, when executed by computing system 500 in general or processing system 501 in particular, direct computing system 500 or processing system 501 to execute an application that generates a web service request, execute a client security component of the application to include security information in the web service request, and utilize a mobile application programming interface to transfer the web service request including the security information for delivery to a web server.

Software 505 may include additional processes, programs, or components, such as operating system software or other application software. Examples of operating systems include Windows®, iOS®, and Android®, as well as any other suitable operating system. Software 505 may also comprise firmware or some other form of machine-readable processing instructions executable by processing system 501.

In general, software 505 may, when loaded into processing system 501 and executed, transform computing system 500 overall from a general-purpose computing system into a special-purpose computing system customized to facilitate security of an application as described herein for each implementation. For example, encoding software 505 on storage system 503 may transform the physical structure of storage system 503. The specific transformation of the physical structure may depend on various factors in different implementations of this description. Examples of such factors may include, but are not limited to the technology used to implement the storage media of storage system 503 and whether the computer-storage media are characterized as primary or secondary storage.

In some examples, if the computer-storage media are implemented as semiconductor-based memory, software 505 may transform the physical state of the semiconductor memory when the program is encoded therein. For example, software 505 may transform the state of transistors, capacitors, or other discrete circuit elements constituting the semiconductor memory. A similar transformation may occur with respect to magnetic or optical media. Other transformations of physical media are possible without departing from the scope of the present description, with the foregoing examples provided only to facilitate this discussion.

It should be understood that computing system 500 is generally intended to represent a computing system with which software 505 is deployed and executed in order to implement application 506, validation process 200, and variations thereof. However, computing system 500 may also represent any computing system on which software 505 may be staged and from where software 505 may be distributed, transported, downloaded, or otherwise provided to yet another computing system for deployment and execution, or yet additional distribution. For example, computing system 500 could be configured to deploy software 505 over the internet to one or more client computing systems for execution thereon, such as in a cloud-based deployment scenario.

Communication interface 507 may include communication connections and devices that allow for communication between computing system 500 and other computing systems(not shown) or services, over a communication network 511 or collection of networks. In some implementations, communication interface 507 receives dynamic data 521 over communication network 511. Examples of connections and devices that together allow for inter-system communication may include network interface cards, antennas, power amplifiers, RF circuitry, transceivers, and other communication circuitry. The aforementioned network, connections, and devices are well known and need not be discussed at length here.

User interface 509 may include a voice input device, a touch input device for receiving a gesture from a user, a motion input device for detecting non-touch gestures and other motions by a user, and other comparable input devices and associated processing elements capable of receiving user input from a user. Output devices such as a display, speakers, haptic devices, and other types of output devices may also be included in user interface 509. In some examples, user interface 509 could include a touch screen capable of displaying a graphical user interface that also accepts user inputs via touches on its surface. The aforementioned user input devices are well known in the art and need not be discussed at length here. User interface 509 may also include associated user interface software executable by processing system 501 in support of the various user input and output devices discussed above. Separately or in conjunction with each other and other hardware and software elements, the user interface software and devices may provide a graphical user interface, a natural user interface, or any other kind of user interface.
